                 Key: CXF-1012
                 URL: https://issues.apache.org/jira/browse/CXF-1012
             Project: CXF
          Issue Type: Sub-task
          Components: REST
    Affects Versions: 2.1
            Reporter: Jervis Liu


Section 2.4.3

An implementation MUST catch WebApplicationException and map it to a response. 
If the response 
property of the exception is not null then it MUST be used to create the 
response. If the response 
property of the exception is null an implementation MUST generate a server 
error response. 

An implementation MUST allow other runtime exceptions to propagate to the 
underlying container. This 
allows existing container facilities (e.g. a Servlet filter) to be used to 
handle the error if desired. 

Editors Note 2.2 What to do about checked exceptions ? If we allow them on 
resource methods then do 
we need some standard runtime exception that can be used to wrap the checked 
exception so it can be 
propagated to the container in a standard way ?
